DESCRIPTION
Security-Enhanced Linux secures the gssd processes via flexible manda‐
tory access control.
BOOLEANS
SELinux policy is customizable based on least access required. gssd
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run gssd with the tightest access possible.
If you want to allow gssd to read temp directory. For access to ker‐
beros tgt, you must turn on the allow_gssd_read_tmp boolean.
setsebool -P allow_gssd_read_tmp 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the gssd_t,
you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
gssd_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the gssd_t, you must
turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux gssd policy is very flexible allowing users to setup their gssd
processes in as secure a method as possible.
The following file types are defined for gssd:
gssd_exec_t
- Set files with the gssd_exec_t type, if you want to transition an
executable to the gssd_t domain.
Paths:
/usr/sbin/rpc.gssd, /usr/sbin/rpc.svcgssd
gssd_keytab_t
- Set files with the gssd_keytab_t type, if you want to treat the files
as kerberos keytab files.
gssd_tmp_t
- Set files with the gssd_tmp_t type, if you want to store gssd tempo‐
rary files in the /tmp directories.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
gssd policy is very flexible allowing users to setup their gssd pro‐
cesses in as secure a method as possible.
The following process types are defined for gssd:
gssd_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
